Ah, that is probably an extension. Try this out @maccoy54 :
extension DateFormatter {
init(format: String) {
self.dateFormat = format
}
}
But… what does this have to do with the gifts? 🤔 I believe you entered the wrong gist. Can you double check?

Hello,
I'm trying to use the code and I have a problem with this part with swift 5:
let shortMonthformatter = DateFormatter(format: "MM")
let longMonthFormatter = DateFormatter(format: "MMMM")
fileprivate let yearMonthFormatter = DateFormatter(format: "yyyy-MM")
An idea
Cordially
